Insights
Spontaneous cerebrospinal fluid (CSF) rhinorrhea in children can stem from inner ear issues. Early diagnosis via hearing tests and imaging is crucial for timely surgical repair of these rare congenital conditions.
Area of Science:
- Otolaryngology
- Pediatric Neurology
- Neurosurgery
Background:
- Spontaneous cerebrospinal fluid (CSF) rhinorrhea is a rare condition.
- It can be associated with congenital inner ear malformations.
- Pediatric patients with hearing impairment, rhinorrhea, or otorrhea may have a CSF leak.
Abstract:
Spontaneous cerebrospinal fluid (CSF) rhinorrhea is rare and may develop secondary to inner ear malformation. A possible diagnosis of CSF leak should be considered in any pediatric patient who presents with hearing impairment, rhinorrhea, or otorrhea. Temporal bone computed tomography should be performed in children with hearing impairments. We describe a case of congenital inner ear anomaly in a 12-month-old girl who presented with intermittent rhinorrhea after birth and detected hearing problems when she was 6 months. After diagnosis, the CSF leak was surgically repaired without complications.
